Any places to s.hit and eat in Saratoga Springs/Travers Weekend?

I'm going to be in town Saturday the 28th for the Travers. I'll be staying in my vehicle and would really appreciate a few recommendations on where I can s.hit. Pissing is no problem as I have a jug for that but would really prefer to s.hit in a toilet.

Also would prefer if toilets were in a restaurant that way I could get a bite to eat.
